So if you were one of the people who purchased a CCNA study guide for the 640-802 CCNA exam but never got around to seriously studying and taking the exam, we have some suggestions for you.  First you can use a large portion of your existing CCNA study guide.  You just need to strip out a few chapters(Wireless/Security/Voice) and add a few more in.  So what might that be and how can I supplement my existing CCNA study guide to cover the CCENT 100-101 exam or the CCNA 200-120 exam?

Take a good look at this article which covers what changed on the ICND1, the ICND2 and the composite CCNA exam.

Once you are done reviewing that, head on over to our Free CCNA study guide.
